Using the C SDK to Deliver Data to ThingWorx from a Raspberry PI

Hi @smainente  Good Catch! I did try removing the extra  "/Thingworx" but still getting the same error 

my build is successful too(see below):

Hi @slangley thanks for the response. Do you know any article or steps needed for the configuration. BecauseI used the document (Getting Started with The ThingWorx C SDK on the Raspberry PIhttps://community.ptc.com › iottechtips › UsingT...) from PTC to start with and it did not cover these information. Also, I will try as per your suggestion.
